I'll leave this one to HJ.

This was last changed by commit f9c316c4, which says
    Silence uninitialized warning on ehdr_start_save
    
    Older GCC, like 4.1/4.2, will issue an uninitialized warning on
    ehdr_start_save.  This patch silences by using
    
    struct bfd_link_hash_entry ehdr_start_save = ehdr_start_save;

Blah.  A warning fix for an older gcc that causes a warning in a
newer compiler.
